i was mainly a pot smoker from 18-21 then from 21-24 i switched to alcohol and bars and smoked less weed. alcohol destroys you all around while weed is a little more subtle which fries your mind and turns you into an emotionless drone. i've seen pot suck the life out of many of my friends and myself. most people don't even realize what it's doing to them. and the way pot is celebrated today makes me sick. it's ******* up countless lives.
my first thoughts about quitting probably came around 22 but i didn't have it in me.
i'm 25 now and have 88 days sober.
i'd say get off them both as quickly as you can.
